Our Services
Testing of Isolating Valves and Flow Switches
FSI provides annual testing for these elements. Flow switches indicate which part of the building has a fire so firefighters can quickly locate it. Isolating valves can be shut to enable repairs and maintenance of the fire sprinkler pipework. It is a requirement of NZS 4541 that these are testing routinely.
Hydrant Flow Testing
FSI has the staff and calibrated equipment to conduct multiple hydrant tests to confirm the performance of the hydrant main for use as a fire fighting water supply or as a source of water for a fire sprinkler system.
Backflow Prevention
FSI provides backflow prevention testing annual as required, or in conjunction with the fire sprinkler inspection, to prevent water supply contamination where fire sprinkler systems are connected to portable supplies.
